MEANS FOR CONTROLLING FLOW OF LIQUIDS.

SPECIFICATION forming part of Letters Patent No. 570,436, dated October27, 1896.

Application filed June 4, 1895. Serial No. 551,640. (No model.)

To on whom it may concern.-

Be it known that I, GEORGE O. MOEWEN, a citizen of the United States,residing at Newark, in the county of Essex and State of New Jersey, haveinvented certain new and useful Improvements in Means for Controllingthe Flow of Liquids; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to lettersof reference marked thereon, which form a part of this specification.

This invention relates to a novel form of apparatus for burninghydrocarbon oils or other oils, and is designed for utilization for bothilluminating and heating purposes.

The present invention has for its primary object to provide a novel formof controlling device or regulator for automatically delivering the oilfor consumption which shall be very simple in construction and stillvery reliable in its governing operation, completely shutting off thesupply of oil and avoiding leakage when the burner or burners are notlighted, the construction of my novel form of controlling device beingsuch to regulate the height of the oil in a service-tank and in thefount or founts of the lamps supplied with oil from said tank.

The invention therefore consists in the novel form and construction ofcontrolling device or regulator herein shown and described, and also inthe novel arrangement and combination of the same with other parts ofthe invention, such as will be hereinafter fully described, and finallyembodied in the clauses of the claims.

The invention is illustrated in the accompanying sheet of drawings, inwhich- Figure 1 is a vertical section of a suitable chandelier and lampsprovided with a service-tank and illustrating one arrangement of mynovel form of controlling device in connection with said tank. Fig. 2 isa vertical sec tion of said controlling device on an enlarged scale,illustrating one form of valve construction; and Fig. 3 is a horizontalsection of the same, taken on line 00 in Fig. 2. Fig. 4 is a verticalsection of the controlling device, but illustrating another modifiedform of valve used in connection therewith; and Fig. 5 is still anotherform of valve provided with a tubular form of piston or valve-stem. Fig.6 is a sectional view of still another form of controlling device orauxiliary or supplemental service-tank and valve therein.

Similar letters of reference are employed in each of the above-describedviews to indicate corresponding parts.

In said drawings, 1) designates the main supply-tank, which maybe-placed in any suitably elevated position, either within or'with outthe building, to supply one or more lamps or burners. Connected withsaid tank I) by means of a suitable supply-pipe b is a chandelier A,which consists, essentially, of the upper ornamental section a, forsecuring it to the ceiling, and the pipe a, secured therein andconnected by a suitable connection a with said pipe Z), which can besuitably packed or otherwise constructed to prevent leakage at thatpoint. The lower end of said pipe a is screw-threaded, as shown, and isscrewed into a threaded boss or collar 0, from which extendsuitably-constructed spider-arms 0, having the perforated ends 0 towhich is secured, by means of suitable pins or rivets, the service-tank(I. Said tank is provided with a centrally-perforated cover (1, which isarranged around the pipe a and over said boss or collar 0 and has itsedge d turned down and over the upper circumferential edge of theservice-tank, to which it can be secured in any Well-known manner, aswill be clearly evident. Said tank d is also provided in the bottomthereof with a suitable depression (1 for the connection of thechandelier arms or branches (1 which support and feed the founts (Z ofthe lamps cl.

Of course it will be understood that the form and construction of saidservice-tank 61 may be varied. lVithin said tank d, I have secured asuitable governing or controlling device for completely andautomatically shutting off the supply of oil into the tank cl when theoil rises above a certain level, and the construction of said devicebeing such to automatically open and permit the entrance of a freshsupply of oil into said tank at when the oil has fallen below saidlevel. Said controlling device comprises therein a separateoil-receiving reservoir or chamber 6, which may be of any de sirablcshape and cross-section, and is secured in any suitable manner,preferably within said tank (I, to one of the spider arms 0,substantially as illustrated in Fig. 1. Said reservoir or chamber 6 actsas an auxiliary or supplemental service-tan k,into which the fluid fromthe main supply-tank b is received, and is preferably provided with asuitable cover a, secured to said chamber in any desirable manner, andis connected with the lower end a of the pipe at by a suitable pipe ortube a, which terminates and is secured in a suitable opening 6 in theside or in any other desirable portion 01' said chamber or reservoir 6.In the bottom of said chamber or reservoir 6 is a suitable opening, andin communication with the same is a stand-pipe or other suitable castinga provided with a longitudinally-arranged duct 6 through which the oildeposited in the chamber 6 can pass and flow into the service-tank (1when the valve or controller connected with said stand-pipe or thecasting 6 is open. Said valve or controller consists, essentially, of asuitable piston or valvedisk 6, having an annular anddownwardlyextending rib or flange e, which normally rests upon asuitable packing-ring f, made of any desirable material, and which maybe forced into and held in a depression in the top of the stand-pipe orcasting a, as clearly sho wn in Figs. 2 and 2). Connected with saidpiston or disk a is a stem c", which extends down into and through saidduct 6 leaving sufficient space for the passage of the oil through thesame, and said stem being provided with a bifurcated and perforated enda at the bottom. In place of the stand-pipe 0 (shown in Figs. 2 and 4)said controlling device 6 may be made as indicated in Fig. (3. In saidconstruction the i e a is tapped directly into a tubular portion chaving a duct 6, said portion being formed integral with the standpipeportion 6 The fluid passes down through the duct 6, and through anopening 6 in the pipe portion 6'' at one side thereof, as indicated indotted lines, and finally through the top of said pipe into the tank (Z.The valvedisk 6 on the stem 0 may rest in a conical seat at the top ofsaid pipe or casting 6 substantially as shown, in which case I maydispense with the packing f. Pivotally supported in a suitable bracketg, as shown in Figs. 1 and 2, is a suitable float h, having an arm 72which is also pivotally connected with the bifurcated end of said stem 6Said float, which is preferably of the construction shown, but may bemade in the shape of a lever or other similar device, is of such aconstruction that it will rise and fall with the varying levels of thefluid in the tank (1, thereby correspondin gly operating the valve-stem,and hence the piston or valve-disk 6 which is brought down upon orraised from the packing-ring f or its seat at the top of the stand-pipeor casting 6 Thus it will be seen that when the oil in the tank d is atthe level indicated in Fig. 1 said valve is closed, but as the fluid isbeing consumed by the lamps or burners and falls below said level in theservice-tank cl, an upward movement of the valve-stem c is the result,causingthe valve at the top of the stand-pipe or casting to be openedand a fresh supply of oil to pass into the tank d, and as soon as theoil therein has again reached its former level indicated in Fig. 1 saidvalve-disk e is again tightly closed down on the packing-ring f or uponthe valve-seat at the top of the pipe or casting 6 thereby completelyshutting off the supply of oil into'the tank cl until a fresh supply isneeded. In lieu of the construction of valve illustrated in said Fig. 2,the casting 6 may be made in the manner of a hollow cylinder and thepacking f can be secured directly to the under side of the valve-disk orpiston a, being brought down upon the surrounding edge of the saidcylinder when the valve is closed to shut off the supply of fluid, asclearly illustrated in Fig. 4. If desirable, said valve-stem 6 may bemade hollow, as indicated in Fig. 5, being provided with suitableperforations e, through which the fluid can flow into said hollow stemand finally down into the tank cl, as will be clearly un derstood froman inspection of said Fig. 5. By this arrangement of the valve-disk e atthe top of the pipe or casting e the column of oil in the chamber orreservoir 6 will by its own pressure act 011 the top of said disk, andin addition to the weight of the valve-operating mechanism will help tomaintain said. valve-disk closed tightly down upon or against thepacking-ring f or upon its seat when the level of the fluid in the tankcl is below the level indicated in said Fig. 1, thereby securing anabsolute stoppage of the flow of liquid from the chamber 6 into the tank(1.

Of course it will be evident that my novel form and construction ofcontrolling device is applicable to many other purposes and apparatusfor automatically controlling the flow of liquids from one reservoir ora pipe into a second reservoir or pipe, and I therefore do not limit myinvention to its use in connection with lamps for burning hydrocarbon orother oils. It will also be evident that many changes of constructionmay be made in the details of the arrangements and combinations of theparts herein shown without departing from the scope of my invention, andI therefore do not limit my invention to the exact arrangements andcombinations of parts herein shown and described.

Having thus described my invention, what I claim is- 1. In a device forcontrolling the flow of liquids, the combination with a service-tank.and means for conducting liquid into the same; of a separate chamber orreservoir arranged within said tank; a stand=pipe in said chamber orreservoir leading from the same into. said service-tank; a valve at thetop of said stand-pipe held closed by the pressure of the column ofliquid 3 and means connected with said valve and operated by the riseand fall of the liquid in the service-tank to control the movement ofsaid'valve.

2. In a device of the class described, the combination with aservice-tank and means for conducting liquid into the same; of a chamberseparate from and Within said tank;

a stand-pipe in said chamber communicating with the service-tank a valvefor said standpipe held closed by the pressure of the column of liquid;a float; and means connecting said float with the valve.

3. In a device of the class described the combination with a burner of aservice-tank GEO. G. MCE'WEN.
